Abstract
A U-tube installation device used for the underground construction of a ground-source heat pump comprises a U-headed bolt rod and a connecting sleeve, wherein the U-headed bolt rod is used for the connection of a U-tube, and the connecting sleeve is arranged at the top end of a connecting rod used for the installation of the U-tube. The bolt rod and the connecting sleeve are not connected directly, whereas the connecting sleeve of the connecting rod used for the installation of the U-tube is sleeved into the bolt rod in certain combination length, so that pushing the connecting rod can exert downward force onto the U-head and the U-tube can be pushed to overcome the effect of such reverse forces as the buoyancy of water or slurry in a ground-source well and the friction of the well wall to approach the well bottom and take the position. As the bolt rod and the U-tube are not connected directly, the bolt rod and the U-tube can separate naturally and then the connecting rod can be taken out, which can guarantee the speed and quality of the construction better than the mode that a traditional U-tube installation device impacts downwards directly without adopting a sleeve. The utility model can realize fast connection and tube installation and can fast lift the connecting rod when the tube is in place. In addition, the utility model has the advantages of convenient on-site operation, strong practicability, safety, reliability, low cost and good application effect in the tube installation construction of ground-source wells.
Description
Technical field
The utility model relates to a kind of soil source heat pump down-hole pipe device under the special-purpose U type pipe of constructing, and belongs to soil source heat pump well-digging construction process technical products field.
Background technique
Earth source heat pump heat supply and air-conditioning cold supply system have the energy that makes full use of underground, the advantage that employing one cover system can solve annual air-conditioning cooling and heat supply problem, soil source large-scale promotion use in recent years, and obtained good application benefit.Soil source heat pump system utilizes the natural energy of underground ground to be used for air-conditioning cooling, heating and heats water, itself does not pollute and consumes underground water, has all obtained to develop rapidly aspect two of technical products and practical applications, and has had the vast market potentiality.But because the composition complexity of underground rock-soil layer, the well-digging construction is subjected to the influence of geological state, and engineering time and expense all expend bigger, thereby causes the application area of the air conditioning hot solution of this effective practicality to be subjected to bigger restriction.Therefore, how further to improve construction process targetedly, construction speed and quality are provided, reduce construction cost, be that present earth source heat pump is applied the very important development field in field, wherein the Placement of the U head of joint, U type pipe bottom and following effective connecting rod is the improved importance of construction process when managing down.
In the well-digging construction of present source, ground, directly use during following pipe by under manage connecting rod and withstand U type pipe and connect and use the U head, connecting rod occurs at following Guan Zhonghui and deviate to cause U type pipe is pushed up the situation of breaking, influence construction quality and progress.Employing effective connecting rod top under U type pipe connects a coupling sleeve, being inserted in the bolt shank that U type pipe connects with the U head descends to manage, it is a kind of method of practical convenient, if but both structures, size mismate, the situation that causes pushing up disconnected U type pipe also can appear breaking away from, therefore need further to optimize and improve, to guarantee construction quality and progress better.
Summary of the invention
The purpose of this utility model and task are, at the problems referred to above that exist in the present soil source heat pump well-digging construction process, develop a kind of soil source heat pump down-hole pipe device under the special-purpose U type pipe of constructing, adopt telescopic Placement, the coupling sleeve (2) on effective connecting rod top under effective bolt shank (1) under the U type pipe and the U type pipe is realized directly contacting but not direct rigidly connected mode, and guarantee suitable to length, can realize faster, pipe connects down reliably, improves construction quality and progress.
Specific descriptions of the present utility model are:
A kind of soil source heat pump down-hole pipe device under the special-purpose U type pipe of constructing, comprise that U type pipe connects the coupling sleeve two-part composition with effective connecting rod top under the bolt shank of U head and the U type pipe, wherein directly be not rigidly connected between the bolt shank of U head (1) and both inwalls of coupling sleeve (2), but both directly contact.In the friction pair with coupling sleeve (2) composition on the top of effective connecting rod (3) under bolt shank (1) the insertion U type pipe of U head, coupling sleeve (2) is placed in the outside of bolt shank (1).Promote connecting rod when managing down and can apply downward power the U head, and promote U type pipe to overcome opposite force effect such as the buoyancy of water in the soil source well or mud or wall friction power and to go downwards to the shaft bottom in place, when taking out connecting rod, because bolt shank and U type pipe do not have and anyly directly be connected, can break away from naturally and cooperate and the taking-up connecting rod.
Coupling sleeve (2) is welded in down the top of effective connecting rod (3).Be being rigidly connected between the other parts of bolt shank (1) and U head by bolt.
The length that bolt shank (1) stretches into coupling sleeve (2) is 100～600mm, and more excellent length range is 300～500mm.
The utility model than not adopting sleeve directly down the mode on top be easier to guarantee the speed and the quality of constructing, control simultaneously is suitable, and both do not break away from can guarantee down to manage in conjunction with length the time, to avoid damaging U type pipe.Adopt this device can realize connecting fast pipe down, carry connecting rod on again can be fast after following pipe is in place, execute-in-place conveniently, practical, safe and reliable, cost is very little, effect is good in the pipe construction of soil source down-hole.
